Questions;
Do you have to memorize a Metamagic spell feat along with the spell you plan to use it on when you memorize your daily spells?
Is there a rule about if you have left an open spell slot and a have a spell that you want to apply a metamagic feat to that a you can move that spell up to the open spell slot? Example: My wizard has memorized Burning Hands as a 1st level spell, has an open 4th level spell slot, and the Maximize Spell feat. Can he Maximize the Burning Hands spell he has already memorized which would move it to the open 4th level spell slot?
What happens when you cast large area spells in confined spaces? Does the spell try to fill the necessary area and travel along the corridor? Example: My 5th level wizard casts Fireball down a 10ft wide corridor. The Fireball explodes in a 20ft area of fire. Does the Fireball fill the corridor till it fills the equivalent 20ft area?
Thank you for your future assistance.
